R v CASSIDY

The case of *R v Cassidy* concerned an appeal against sentence. The appellant, Cassidy, had been sentenced by the District Court to a head sentence of 16 years imprisonment, with a non-parole period of eight years. The appeal was heard by the Supreme Court of South Australia, constituted by Kourakis CJ, Peek and Nicholson JJ.

The central legal issue before the Full Court was whether the head sentence imposed by the District Court was manifestly excessive, thereby providing grounds for appellate interference. This involved considering the principles governing the imposition of cumulative sentences, particularly in circumstances where an offender has a history of prior offending and the total sentence represents a significant escalation from previous penalties.

The Court reasoned that while a graduated approach to personal deterrence is permissible, especially for younger offenders or those at the lower end of the criminal calendar, there are limits to the linear accumulation of sentences. The Court referred to *R v Flentjar* where Zelling J discussed the principle that a cumulative sentence may exceed the typical sentence for a single offence of that kind, but noted that a significant jump in the total head sentence from previous maximum sentences can be excessive. In Cassidy's case, the Court found that the jump from a previous highest sentence of approximately 21 months to a head sentence of 16 years was too high. The relatively low non-parole period fixed by the sentencing judge was also considered an indicator that the head sentence was excessive, particularly given the offender's poor prospects of rehabilitation. The Court also noted that a small extension of one year by the Magistrate when increasing the head sentence by four years suggested that the cumulative sentence imposed was too high.
